Subject: Bent-pin analysis
Message:
I am going to do a "bent pin analysis" in one of our projects.This is to show that any single short circuit occuring as a result of a bent pin in one connector doesnt have an adverse effect on the equipment. Can anyone help me with analysis background information for this type of analysis?

After a very detailed search of the Reliability Analysis Center's library and databases, we could not find previous procedures for bent pin testing. Since the staff has not experienced this type of testing, we cannot give any guidance.

You will be "plowing new ground" here. I suggest using an FMECA approach [per MIL-STD-1629A Task 102] where you consider all pins in all connectors. What happens when each pin (in turn) contacts each adjacent pin (one at a time) would constitute failure modes you would have to analyze for failure effects. This might be a time-consuming analysis. Bent pins are definitely "real world" conditions and analyzing them could prove useful.
